Get buddy the help needed

Hi there, as many know I posted yesterday morning that our baby buddy who we rescued from the shelter got out and was hit by a car, he is recovering but these vet bills are way out of what I can afford alone, I am asking even if it's a little bit to help he needs surgery and will need physical therapy. I hate to ask for help, but anything please and thank you. He is currently at the crossroads vet in tijears. thank you
